Abstract

A thermo-viscoplastic constitutive model is used in an explicit finite element analysis to determine the strain distribution that develops during rod rolling. The computed strains are then used to predict the resulting grain size of the material microstructure. Predictions are compared to experiments conducted on rolling of square billets. There is good agreement between the measured and predicted roll loads and torques as well as on the deformed geometry. The ability of the analysis to predict the resulting heterogeneous microstructure is also demonstrated.
